Mr. Howard tells us how he gathers and outputs weather information to the Web using Linux, Perl and automated FTP.
Unresolved Issues

One of my main concerns is lightning. Fortunately, our site is in a wooded area that is somewhat protected from direct lightning strikes. Still, I would feel even better if the remote weather sensors were electrically isolated from the display unit and my Linux machine. Some sort of optical isolation would probably work.

Also, I may have to develop an automated way to set the clock on the weather display unit.

Otherwise, the system seems to be working pretty well. With weatherd.pl running from the inittab, and with loop.pl in my startup rc files, the weather station monitoring continues after a reboot without manual intervention. Power loss or server failure will interrupt the service, but neither of those are common occurrences.

My weather station web page (see Figure 3) can be found at http://www.frii.net/~daylight/wscurrent.html. Please stop by and check it out. If you have the opportunity, come to Estes Park and see what a beautiful place it is.

All listings referred to in this article are available by anonymous download in the file ftp.linuxjournal.com/pub/lj/listings/issue56/2538.tgz.

Chris Howard (daylight@frii.net) noodles around with Linux stuff in Estes Park, Colorado, where the winters aren't too cold and the summers aren't too hot, and the view out the window is always beautiful.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
